Professional manufacturer of bell-type annealing furnace
Function: provide heating protection for annealing material Design features: Design features: corrugated inner cap made of stainless and heat-resistant steelcan increase the strength of inner cap, increase the area of heat absorption and heat dissipation, and extend the service life. The sealing flange processed by thebottom is pressed on the base sealing ring through the hydraulic locking device, forming a closed space. The guide devices on both sides enable it to be placed correctly on the base. Each cooling cap include: Spin-formed heat-resistant steel head Spin-formed corrugated cylinder Machined sealing flange Cooling water tank, water tank, etc by sealing checking Cooling water quick manual joints and valves, pipelines Clamp lifting device made of heat-resistant steel and spray overflow ring
Work base pipeline valve station Function: Monitoring and control of safety gas, protective gas filling, exhaust gas and oil and water discharge, working pressure inside the furnace, cooling water, etc. Design features: Each set of valve bracket is mainly composed of gas shunt, exhaust gas shunt, hydrogen charging shunt, nitrogen purging and safety protection shunt, process water shunt, work base cooling water shunt and so on. The flow or pressure of all media is collected by the instrument on the valve station and transmitted to PLC for interlocking control.
Function: Annealing process cooling is realized for the bell-type furnace Design features: The cooling cap is made of heat-resistant steel plate and reinforcedwith section steel. The lower part has supporting legs, the upper part of the shell is equipped with a cooling fan, and the top is equipped with a sprinkler head. With a water small nozzle, The inner cap can be cooled by wind and water respectively to speed up the cooling, improve The productivity. The cooling cap is provided with a lifting device at the top, and the guiding devices on both sides enable it tobe placed correctly on the base. Equipped with electrical and cooling medium quick connector.
Gas heating cap
The heating cap is insulated with heat-resistant fibers and equipped with a new high-speed burner for extremely low exhaust emissions. High-speed combustion efficiency and low energy consumption are achieved by good heating of the heating cap and combustion of the combustion air in a large central heat exchanger to over 450℃.The device can also be equipped with an electric heating system.
Function: Carrying the material roll to achieve strong convection circulating heat transfer to ensure uniform heating temperature of the product. Design features: All stainless heat resistant steel shell and diversion and diffusion system, filled with aluminum silicate insulation material, scientific design, wind conductivity, good insulation performance, continuous work without deformation, used for carrying workpiece, material coils, inner cap, outer cap, etc. Water-cooled furnace fan is installed inside. SKF bearing imported from Sweden is adopted for bearing and balancing test. Each motor is equipped with thermistor for overheating protection. The inlet, exhaust and cooling water interfaces are all on the seat, and two double thermocouples are installed on the work base, which are introduced by the seat for temperature monitoring of the charging chamber. Aproximity switch is mounted on the seat to detect whether the inner cap, heating cap and cooling cap are fastened. Two guide rods are used for accurate positioning of the work base and inner cap. The sealing surface of the work base is embedded with a silicone sealing ring that is resistant to temperature and corrosion. The inner cap and the work base are tightly clamped together by hydraulic locking, which ensures the reliability of the sealing of the work base and inner cap. Each cooling cap include: Semi-open work base seat with insulation material, including flanges, cooling tank and metal hoses, fittings, etc. Heat resistant stainless steel diversion difusion system Temperature measuring instrument and wire Three cap pedestal Hydraulic locking cylinder, among half with self-locking function Temperature resistant silicone rubber sealing ring Work base positioning column and three cap guide column Inlet and outlet piping Work base fan, with motor water cooling system and thermistor protection
