Problems solved by technology

The existing large flanges are all made of stainless steel, mainly because stainless steel does not generate eddy currents and does not generate heat during induction heating in an induction furnace, which can protect the sealing ring from being burned out. The disadvantage is that the price and processing cost of stainless steel are high, and the production cost is too high. Big

Embodiment Construction

[0007] The outer wall 1 of the furnace cover made of ordinary steel and the inner wall 3 of the stainless steel furnace cover are installed on the flange 2 of the ordinary steel furnace cover, and the lower part of the inner wall of the stainless steel furnace cover is lined on the inner side of the ordinary steel furnace cover flange to form a composite furnace cover flange; Furnace body wall 7 and stainless steel furnace body 6 are contained on the common steel body of furnace flange 5, and the top of stainless steel furnace body is lined on the inner side of common steel body of furnace flange, forms composite type body of furnace flange. Taking the furnace body with a diameter of 1-1.5 meters as an example, the cross-section of the large flange is (60-80)×(40-60) mm, and the thickness of the inner stainless steel plate is 5-12 mm. Seal with sealing ring 4 between the furnace cover flange and the body of furnace flange, between the outer wall of the furnace and the furnace g...

Abstract

The present invention relates to a kind of large flange for tight connecting furnace cover and furnace body of induction smelting furnace and induction sintering furnace. It includes furnace cover flange and furnace body flange, and is made up by using general steel, and is lined with stainless steel plate and made into large flange with composite type structure. It can protect sealing ring from burning, and can reduce production cost.

Description

technical field [0001] The invention relates to a large flange for connecting and sealing the furnace cover and the furnace body of an induction melting furnace and an induction sintering furnace. Background technique [0002] Induction furnace cover and furnace body seal The large flange includes a furnace cover flange and a furnace body flange, and a sealing ring is used to seal between the two flanges. The existing large flanges are all made of stainless steel, mainly because stainless steel does not generate eddy currents and does not generate heat during induction heating in an induction furnace, which can protect the sealing ring from being burned out. The disadvantage is that the price and processing cost of stainless steel are high, and the production cost is too high. Big. Contents of the invention [0003] The purpose of the invention is to research a large sealing flange for the furnace cover and the furnace bod...
