Pull-jacking type lengthwise graphitization furnace

Abstract

The invention relates to a resistance furnace in the carbon metallurgy technology, in particular to a pull-jacking type lengthwise graphitization furnace, which comprises two or more than two pull cylinders and thrust cylinders. Piston rods of the thrust cylinders are connected with conductive electrodes at a furnace end, the pull cylinders and the thrust cylinders are fixedly mounted on a head beam of a trolley at the furnace end, each pull cylinder is detachably connected with one end of a pull rod, the other ends of the pull rods are detachably connected with a tail beam of a trolley at a furnace tail, conductive electrodes at the furnace tail are connected with the tail beam of the trolley at the furnace tail, the conductive electrodes at the furnace end and the conductive electrodes at the furnace tail are correspondingly arranged in a furnace body, and the axis of the conductive electrodes at the furnace end and the axis of the conductive electrodes at the furnace tail are positioned on the same straight line. The pull-jacking type lengthwise graphitization furnace solves the problem of uneven jacking pressure, and compared with the prior art, the furnace adopting the ingenious design way enables stress at the furnace end and the furnace tail to be completely centralized on the head beam of the trolley at the furnace end, so that jacking pressure of the furnace end and the jacking pressure of the furnace tail are stable and consistent.

Description

technical field [0001] The patent of the invention relates to a resistance furnace in carbon metallurgy technology, specifically, it belongs to a new type of graphitized resistance furnace body. Background technique [0002] In the carbon industry, in order to enable graphitization of carbon products, increase the degree of graphitization of products, and make the carbon lattice structure of the product close to that of ideal graphite, it is necessary to heat treat the carbon blank at a high temperature above 2800 °C , this heat treatment process is usually carried out in a graphitization furnace. There are two types of graphitization furnaces commonly used, namely Acheson graphitization furnace and serial graphitization furnace. Acheson graphitization furnace is to install the carbon blank vertically or horizontally into the furnace body, and fill the gap between the blanks with coke particles as a resistance material, and the carbon blanks and coke particles together form...

Problems solved by technology

[0004] In view of this, the purpose of the present invention is to provide a top-pull graphitization furnace connected in series to solve the problem of uneven force on both ends of the original top-push graphitization furnace carbon blank column, attenuation of single-sided pressure, and failure to ensure double-sided push pressure. The shortcomings of balance can effectively improve the operation stability of the furnace and reduce the power transmission time, so as to achieve the purpose of improving product quality and reducing power consumption
