Closure heating type metal leakage furnace

Abstract

The invention provides a closed heating type metallic cementation furnace which comprises a furnace body and an internal furnace arranged inside the furnace body, an internal furnace door arranged on the internal furnace, wherein, the internal furnace is a liner which is fully arranged in an inner chamber of the furnace body; the internal furnace door is arranged on the sidewall of the internal furnace. The closed heating type metallic cementation furnace has the advantages of saving electrical energy and metallic material, protecting environment and improving efficiency; a workpiece is evenly heated in the internal furnace; a filter layer has excellent quality.

Description

technical field [0001] The invention relates to metal surface metallization technology, in particular to a closed heating type metallization furnace. Background technique [0002] The existing powder metal infiltration (zinc, aluminizing, zinc-aluminum and other multi-metal co-infiltration) equipment is a horizontal rotary furnace, and the form of the furnace body is generally divided into three categories. 1. Split type (upper and lower furnace body combination); 2. Huff type (left and right furnace body combination); 3. Track type (furnace body is shifted by ground track). Such as figure 1 It is a kind of metal infiltration equipment with split furnace body structure. It includes a furnace body seat 11, an upper furnace body 12, a lower furnace body 13, a furnace furnace 14, a power mechanism 15, an axle 16, a front and rear support wheel 17, a roller 18, a wheel belt 19 and a pressure regulating assembly 10. One end of the furnace is provided with a furnace door 141, a...

Problems solved by technology

[0003] 1. The furnace door is opened at one or both ends of the furnace (inner tank, cylinder) leading out of the furnace body, so that the furnace furnace extending outside the furnace body consumes huge heat energy and wastes energy;

[0004] 2. The furnace temperature is unbalanced, the temperature from the inside of the furnace to the part near the furnace door is decreasing, and the thickness of the infiltration layer of the workpiece near the furnace door is too small, resulting in waste of rework and no guarantee of quality;

[0005] 3. Since the furnace door is set on the end face of the furnace, the infiltrated workpiece can only be displaced in the horizontal direction when entering and exiting the furnace. It is necessary to design special traction mechanical equipment. At present, there are very few such equipment in China, and none of them meet the ideal requirements.

In order to solve the problem of workpieces entering and exiting the furnace, some manufacturers are equipped with forklifts for traction, which is cumbersome to operate;

[0006] 4. Due to the horizontal feeding and discharging method, part of the charge (powder) will inevitably be taken out of the furnace, causing dust and leakage. The production environment is extremely harsh, which not only seriously affects the health of workers, but also wastes valuable production. raw material
