Laboratory box furnace price, Anhui gas roasting furnace

Description :

　　Scope: Large gas furnaces are non-standard energy-saving periodic operation furnaces, mainly suitable for heating in heat treatment workshops of steel mills, special steel, mechanical processing, chemical machinery, heavy industry, metallurgical smelting, casting, forging, flange rings, steel components, wire drawing, environmental protection equipment, mechanical supporting enterprises, loaders, diesel engines, military and other industries.

　　Temperature requirements: Large gas furnaces are divided into high-temperature furnaces, medium temperature furnaces, and low-temperature tempering furnaces. The maximum operating temperature of high-temperature furnaces is within 1200 ℃, medium temperature furnaces is within 950 ℃, and low-temperature tempering furnaces is within 650 ℃. They are selected according to their respective product characteristics, and the furnace size and load capacity are ordered according to customer requirements.

　　Control: Contactors, thyristors, solid-state, modular, electronic digital display, intelligent digital display, computers are used for control PID、PLC、 Remote control, centralized control, programming control, recording with central garden diagram, long circle diagram with multi-point paper recorder, and can also use LCD paperless recorder for recording.

　　Structure: The furnace body is constructed using a module made of full fiber aluminum silicate spinning blanket. The furnace bottom is made of lightweight insulation bricks and heavy refractory bricks. The heating elements are made of resistance wires and resistance belts. The furnace shell is made of steel plates and section steel. The furnace door and trolley are mechanically driven; The specific configuration is designed and equipped according to customer and furnace temperature requirements.

　　Heat treatment products: Suitable for heat treatment of various processed parts, such as stainless steel solid fusion, high manganese steel quenching, valves, flange rings, pressure vessels, rolling rods, steel pipes, steel wires, steel balls, castings, forgings, cast iron, rolling rolls, blades, high-speed steel, tool steel, automobile axles, diesel engine gearboxes, mining machinery, loader bridge arms, etc.
