A gear-tooth-driven melting and casting furnace cover

Abstract

The invention relates to a gear tooth driving type melting and casting furnace cover. The gear tooth driving type melting and casting furnace cover comprises a furnace body casing and a cover body arranged on the furnace body casing in a hinging way, wherein loop seats are separately arranged at the upper end and the lower end, close to the cover body, of the furnace body casing; two inserted pins which are correspondingly adapted with the loop seats are arranged on the cover body along the vertical direction in a sliding way; each inserted pin is hinged to the left end ofa connecting rod; a rack is jointly hinged to the right sides of the two connecting rods; a gear is meshed with the rack; a rotating shaft is connected to the gear; and a rotating handle is connected to the upper end of the rotating shaft. According to the gear tooth driving type melting and casting furnace cover disclosed by the invention, the simplicity in operation is realized; and the opening and the closing of the cover body can be easily controlled by controlling different rotating directions of the rotating handle in a gear tooth driving mode.

Description

technical field [0001] The invention relates to metal heating equipment, in particular to a gear-tooth transmission type melting and casting furnace cover. Background technique [0002] Casting is a method in which materials are directly cast into products after being melted at high temperature. It is generally melted in an electric arc furnace, then poured into a high temperature resistant mold, and then cooled, crystallized, annealed or cut into products. In production, the melting atmosphere, melting temperature and cooling conditions are mainly controlled to ensure high production efficiency, crystallization meets requirements and network structure is formed. [0003] Generally speaking, the structure of the furnace cover of the traditional melting and casting furnace for copper is often complicated due to the need to ensure the sealing of the furnace, which brings huge operational difficulties to the user and indirectly affects the melting and casting effect of copper ...
