Method for improving furnace body dynamic balance of horizontal type converting furnace for non-ferrous metal metallurgy

Abstract

The invention provides a method for improving furnace body dynamic balance of a horizontal type converting furnace for non-ferrous metal metallurgy. The method particularly comprises the steps of endsocket cutting, pre-positioning, pre-aligning, fine-aligning and welding. The process steps are simple, scientific and reasonable; the position and supporting mode of a supporting body are reasonablyset under the condition of lengthening the length of the furnace body, thereby effectively ensuring the purpose of the dynamic balance of the furnace body after lengthened, ensuring normal and stablerunning of the furnace body, increasing the yield, being capable of reducing the cost of repurchasing a second-stage supported bottom-blowing furnace, shortening the construction period, and effectively improving the economic benefits of enterprises.

Description

technical field [0001] The invention belongs to the technical field of horizontal blowing furnaces, and in particular relates to a method for improving the dynamic balance of a horizontal blowing furnace body for nonferrous metal smelting. Background technique [0002] The furnace structure used in non-ferrous metal smelting is composed of a set of furnace body device, two sets of supporting devices, and a set of transmission device. The motor of the transmission device drives the reducer and then drives the ring gear through the pinion to realize the rotation of the furnace body. The furnace body is made of steel plate rolled and welded into a cylindrical shape, with welded heads at both ends. According to the requirements of the smelting process, the required furnace mouth, oxygen gun mouth, etc. are opened on the furnace body. The interior of the furnace body is lined with refractory materials to meet the needs of high-temperature smelting. The supporting device is com...

Problems solved by technology

Building a new furnace is equivalent to building a new factory, and the investment cycle is long; while the transformation of the old furnace is the best solution, but the transformation of the old furnace is not only to lengthen the length of the furnace body, but also requires the transformed furnace body to fully meet the production needs. Among them, How to solve the dynamic balance of the furnace body after the transformation and lengthening is very important. If there is an increased jump when the furnace body rotates, it will cause serious production accidents or lead to the serious consequences of scrapping the original furnace body.
