The front chamber of the sealed box-type furnace is not only the transition area for the incoming material, but also the output area after the workpiece is heated for quenching and slow cooling.D2020-2 CNC DRILLING MACHINE FOR STEEL PLATE To be able to quench, there should be an oil tank under the front chamber; to be able to cool slowly, the top or side of the front chamber should be connected to a slow cooling chamber. During feeding, discharging, quenching and slow cooling, the tray and the workpiece must move back and forth and up and down. The forward and backward movement is completed by a push-pull feeder, and the up and down movement is completed by a lifting mechanism.HD6040-1 CNC GANTRY MOVABLE HIGH SPEED DRILLING MACHINE The front room can be divided into a slow cooling room and a slow cooling room.

According to the movement form of the main air flow in the furnace, there are four basic types of calciner: swirl type, spray type, suspension type and fluidized bed type. In these four types of calciners, raw materials and fuels are dispersed in the airflow by "swirl effect", "spray effect", "suspension effect" and "fluidization effect" respectively.How to Update your heat treatment Most of the calciners developed in the early stage mainly rely on one of the "four effects" mentioned above. Later, various types of calciners penetrated each other technically, so most of the current calciners tend to use the "comprehensive effect" of the above effects, in order to optimize the heat transfer, mass transfer, momentum transfer and chemical energy transfer in the calciner. Aluminum alloy micro-channel cooling plate vacuum gas quenching Reaction process (referred to as "three passes and one reaction" process). That is to follow the principle of "taking the high dispersion of materials as the premise, taking the high efficiency and complete combustion of fuel as the key, aiming at the effective decomposition of raw materials, and taking environmental protection and social responsibility as our responsibility!" to improve and perfect the calciner.SEMI-AUTOMATIC CONTROL HORIZONTAL STRAIGHT CUTTING BANDSAW G4230-50 FLS series calciner refers to a series of calciner developed by F.L.

During the whole working process, the trolley bears its own weight, the weight of the grate bar, the weight of the sintered ore and the effect of the negative pressure of the draft, and it also receives repeated heat for a long time, so it produces a lot of thermal fatigue. The performance of the trolley directly affects the use of the sintering machine.

The cooling water tank leaks. If water leaks, the surface color of the quenched product will be blue-gray, and there will be peeling on the surface in severe cases. The reason is that the cooling water tank of the mesh belt under the quenching furnace leaks water into the inner cavity of the mesh belt, and the water is gasified and then goes upward. Push it into the furnace hall to oxidize and decarburize the surface of the product. The remedy is to find the leak point and weld it firmly, or replace the cooling tank with a new one.LMX-4228 CNC GANTRY MACHINING CENTRE From the surface color of the air leakage and decarburization products, it is slightly whiter than the normal color, unnatural, and has serious peeling phenomenon.

Electric push rods generally use two-stage transmission. There are mainly two types of primary transmission deceleration, one is to use worm gear for deceleration, and the other is for gear deceleration; most of the two-stage transmission uses screw nuts. Its working principle is briefly described as follows:HORIZONTAL MITRE BAND SAW MACHINE BS-180G The motor output shaft worm drives the worm wheel to rotate, which makes the screw connected in the worm wheel rotate, and the nut on the screw moves axially in the guide tube. When the required stroke is reached, the nut boss presses down the travel switch to cut off the power, and the motor stops. The positive and negative controls are the same.HORIZONTAL MITRE BAND SAW MACHINE BS-215G After the motor is decelerated by the gear, it drives a pair of screw nuts, and the nuts are connected to the push rod, so that the rotational motion of the motor becomes the linear motion of the push rod, and the forward and reverse rotation of the motor is used to complete the push rod action. Through mechanisms such as various levers, rockers or connecting rods, complex actions such as rotation and shaking can be completed. By changing the length of the lever arm, the stroke can be increased or increased.Aluminum alloy micro-channel cooling plate vacuum gas quenching The electric push rod is a new type of electric actuator, which is mainly composed of a drive motor, a reduction gear, a screw, a nut, a guide tube, a guide sleeve, a push rod, a mounting seat, a spring, a casing and a worm gear, and a micro-control switch.

Automatic control systems are widely used in various fields, especially in industrial fields, and temperature control is one of the most common control types in control systems. With the rapid development of single-chip microcomputer technology, controlling the controlled object through single-chip microcomputer has increasingly become an important development direction in the field of automatic control in the future. This design requires the design of an electric furnace temperature control system with a single-chip microcomputer.X2.7 BENCH MILL DRILL The temperature control system is mainly composed of four parts: temperature sensor, temperature regulator, actuator, and controlled object. Its system structure diagram. The controlled object is a large-capacity, large-inertia electric furnace temperature object, which is a typical multi-order volume delay characteristic.

Most of the boilers needed by industrial and mining enterprises in production are steam boilers. Steam is mostly used in production where a certain temperature of heat is required to meet the requirements of the production process, such as textile printing and dyeing, food sugar, rubber paper, petrochemical and other industries. Therefore, it is necessary to determine the saturated steam parameters of the boiler in accordance with the requirements of the production process. The advantage of saturated steam is that it can ensure a constant temperature required for production.D SERIES CNC DRILLING MACHINE FOR PLATES Generally, the pressure of the boiler is always higher than the saturated steam pressure required for production, the reason is to overcome the pressure loss in the pipeline or pipe network. At present, in many cases, the boiler nameplate pressure is much greater than the pressure required for production. For example, many users have purchased a 13-pressure boiler, but actually only use the operating pressure of 5 gauge or 6 gauge. Running at such a low pressure has adverse effects on steam quality. Because the pressure decreases, the specific volume of the steam increases, and the flow rate at the outlet increases greatly, so that the phenomenon of steam carrying water increases. Generally, the pressure required for actual production plus the pressure drop required to overcome all pipeline resistance plus 25% to 30% of the pressure margin is enough.D2020-2 CNC DRILLING MACHINE FOR STEEL PLATE The head of the feedwater pump is matched with the nameplate of the boiler. The actual operating pressure of the boiler is too low, and the power consumption of the feedwater pump is obviously a huge waste.Vacuum brazing of surgical forceps - heat treatment process The boiler steam parameters used in small power plants can be configured according to the parameters required by the steam turbine. Most of them use superheated steam at 25 gauge atmospheric pressure. If the turbine is superheated steam with 13 gauge atmospheric pressure, then the boiler should choose the superheated steam parameters with 16 gauge atmospheric pressure, which can make the steam quality better.Aluminum alloy micro-channel cooling plate vacuum gas quenching
