Energy saving high temperature box type heating furnace
Energy-saving type high temperature box furnace rated temperature of 120 DEG C is national standards for energy-saving box type furnace, mainly used for high alloy, alloy steel products, stainless steel or other steel normalizing, quenching, annealing and heating heat treatment.
Characteristics of energy saving high temperature box type heating furnace:
1. The furnace shell made of steel and steel plate welding and, lining by 0.6 super energy-saving light refractory thermal insulation masonry brick and aluminum silicate refractory fiber and;
Insulation powder expansive 2 is filled between the furnace shell and lining aluminum silicate interlayer;
3. Door side of the balance a vertical barrel regulating door weight, such as the discovery of door overweight or underweight with scrap iron regulating balance the weight of the bucket.
4. The heating element is by high resistance alloy wire wound into a spiral, placed on both sides of the furnace and the rear wall of the furnace bottom and the furnace door, heating the workpiece is placed in the hearth of the furnace bottom on, the lift door is carried out through the hand wheel or mechanical transmission, a thermocouple is arranged on the top of the, a is used for temperature detection, another branch as over temperature protection. Special points out that the energy saving type high temperature box type heating furnace is used as a simple protective atmosphere, and the following 750 is strictly forbidden.
