A horizontal high temperature hydrogen resistance furnace

Abstract

The invention relates to the technical field of plate rolling technology equipment, in particular to a horizontal type high temperature hydrogen resistance furnace. The horizontal type high temperature hydrogen resistance furnace comprises a heating furnace and a material loading and unloading device. A double-layer furnace top structure is arranged at the top of the heating furnace, and the heating furnace is connected with the material loading and unloading device through a furnace mouth. A furnace door capable of being opened and closed is mounted on the furnace mouth in a sealed mode, descends to the position in front of the furnace mouth from the position above the furnace mouth, and horizontally moves in the axial direction of the furnace mouth to be pressed on the furnace mouth, sothat sealing of the furnace mouth is achieved. On the basis that the heating requirement for heating large-sized tungsten molybdenum plate blanks before rolling are met, the horizontal type high temperature hydrogen resistance furnace can effectively prevent potential safety production dangers such as hidden bearing dangers and untight sealing from occurring.

Description

technical field [0001] The invention relates to the technical field of plate rolling process equipment, in particular to a horizontal high-temperature hydrogen resistance furnace. Background technique [0002] In the machinery industry, resistance furnaces are mostly used for heating before metal forging, heating for metal heat treatment, brazing, powder metallurgy sintering, glass ceramics firing and annealing, melting of low melting point metals, drying of sand molds and paint films, etc. It uses electric current to make the furnace The internal heating element or heating medium generates heat, thereby heating the workpiece or the workpiece. The hydrogen resistance furnace uses hydrogen to protect the electric furnace, so that the product can maintain a bright color, no oxidation on the surface, and the product scrap rate is extremely low. The application of hydrogen resistance furnace to the heating of tungsten-molybdenum and its alloy slabs before rolling and the anneal...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the existing hydrogen resistance furnace cannot meet the customer's heating requirements for large-sized tungsten-molybdenum slabs before rolling. At the same time, it also faces the hidden danger of load-bearing caused by the large span of the furnace roof, and the existing furnace door structure is inconvenient to open and close. The seal between the furnace body and the furnace body is not tight when it is closed, which may easily lead to hydrogen leakage and cause safety hazards
