Annealing furnace standard energy-saving cycle operation furnace, energy saving structure, fiber structure, electricity saving 30%. Composite high-aluminum porcelain nail set, anti-impact sealing bricks for the trolley, automatic sealing of the trolley and the furnace door, integrated rail, no need for basic installation, can be used on the horizontal ground. Mainly used for high chromium, high manganese steel castings, ductile iron, roll, steel ball, 45 steel, stainless steel and other quenching, annealing, aging and various mechanical parts of the heat treatment. Features: 1, no noise, no environmental pollution. 2, small heat storage, less heat loss. 3, high precision temperature control, furnace temperature uniformity. 4, high degree of automation, simple. 5, can use PID programming setting, automatic operation. 6, good sealing, long and reliable life. Widely used in chemical, petroleum, food, metallurgy, machinery, light industry, electric power, shipbuilding, paper, mining, medicine, central heating and other industrial sectors. With the development of social productivity, its application in various industries is more and more extensive.

2, well type annealing furnace (example: flange ring heat treatment furnace) Use: the furnace is for metal parts, ring parts and other heat treatment equipment at rated temperature introduction: the furnace is composed of a furnace body and a movable furnace cover and control system. 1. The shell of the furnace body is welded with shaped steel and steel plates. 2, the furnace cover support adopts the combination of steel and guide rail mobile. 3. The heating parts are arranged on the furnace side with high resistance alloy produced by Beijing Shougang. 4, the bottom of the furnace due to the use of high aluminum brick masonry, the center of the furnace using a large trap small circle approach, heating inside and outside. 5, the furnace cover adopts hydraulic lifting, motor control automatic walking. 6, temperature control system using PID SCR control, high precision.

Third, the use of box type annealing furnace: the main use of steel workpiece quenching, normalizing, annealing and other conventional heat treatment of the special equipment. Features: 1, the electric furnace load is large, high productivity, especially suitable for small and medium-sized parts of the heat treatment heating, energy saving up to 30%, uniform furnace temperature, intelligent digital display table PID (as shown) automatic control of furnace temperature, high precision; 2, electric furnace loading royal material is convenient, good conditions; 3, the seal of the furnace door and the furnace body is automatically sealed, without manual sealing; 4, the electric furnace is equipped with a chain protection device, which can prevent the failure and accident caused by mistake. Shaded annealing furnace The shaded annealing furnace is mainly used for the annealing of thin plates and the normalizing treatment of steel parts in a natural atmosphere. 1, special steel, precision alloy large fiber trolley type resistance furnace description strip, wire bright annealing. 2. Annealing of special steel casting and forgings. 3, silicon steel sheet finished annealing. 4. Sintering of metal and non-metal powder pressing parts.
