Problems solved by technology

Making 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, otherwise it will Serious consequences that lead to the scrapping of the original furnace body

Embodiment 1

[0023] This embodiment provides a method for expanding the furnace body of a horizontal blowing furnace for smelting nonferrous metals, comprising the following steps:

[0024] Removal of the head and post-processing: cut off the head of one end of the old furnace body by segmented uniform cutting, and polish the cut to obtain the pretreated old furnace body;

[0025] Pre-alignment: First, set up measuring brackets of the same specification in the furnace shell of the newly added section and the inner cavity of the old furnace body for pretreatment respectively, and open a light hole in the center of the measuring bracket, and one of the light holes A laser instrument is set up, and then the laser instrument is aligned with another light hole by adjusting the position of the furnace shell of the newly added section, and finally the furnace shell of the newly added section is pre-welded with the pretreated old furnace body;

[0026] Install and adjust the support body: accordin...

Abstract

The invention provides a capacity increase method of a furnace body of a horizontal type converting furnace for non-ferrous metal metallurgy. The capacity increase method comprises the specific stepsof seal head removal and aftertreatment, pre-alignment, supporting body mounting and adjusting, fine alignment and welding and postweld treatment. The process steps are simple, scientific and reasonable. Under the condition of increasing the length of the furnace body, the position and the supporting manner of a supporting body are set reasonably, normal and stable operating of the furnace body isguaranteed, the yield is increased, the cost for purchasing a bottom blowing furnace in a two-gear supporting manner again can be reduced, the construction period can be shortened, and the economic benefits of enterprises can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of horizontal bottom blowing furnaces, and in particular relates to a method for expanding the furnace body of a horizontal blowing furnace 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 comp...
