Bottom Block Masonry Method of Molten Salt Chlorination Furnace

Abstract

The invention discloses a masonry method of a bottom block of a fused salt chlorination furnace, and relates to the technical field of fused salt chlorination furnace manufacturing. The method comprises the following steps that A, a construction platform is built; B, a load lifting device is manufactured; C, a paper washer is laid on the construction platform, four semicircular small masonry areasare determined by paying off; D, the load lifting device is fixed to the construction platform, and paper washer is provided with partitioning components to separate the four small masonry areas; E,masonry bodies are built layer by layer in the small masonry areas to form a plurality of bottom block layers, wherein the masonry bodies are arranged in an inverted V shape, the masonry bodies of theadjacent bottom block layers are built with seams being staggered, four bottom block bodies are obtained after masonry of the bottom block layers is completed, and the load lifting device penetratesthrough the bottom block bodies; F, the bottom block bodies are dried, G, the bottom block bodies are lifted into the fused salt chlorination furnace; H, the rod of the load lifting device is cut, andpreformed holes are filled with a fire-resistant material; and I, the fire-resistant material is arranged between the bottom block bodies in a filling mode. According to the masonry method of the bottom block of the fused salt chlorination furnace, construction is convenient, and the quality of finished products is good.

Description

technical field [0001] The invention relates to the technical field of manufacturing a molten salt chlorination furnace, in particular to a method for building blocks at the bottom of a molten salt chlorination furnace. Background technique [0002] Molten salt chlorination furnace is the core furnace for producing sponge titanium by molten salt chlorination. The production environment in the molten salt chlorination furnace is complex and toxic, and the working fluid contains CO 2 , NaCl, CaCl 2 , FeCl 2 etc., the molten body produced in the furnace is composed of solid, liquid and gas with a density of 1600-1800Kg / m 3 , the airtightness of the furnace body is required, especially the quality of the masonry is extremely high. [0003] The bottom block of the existing molten salt chlorination furnace is usually built and dried in the furnace, and its disadvantages are as follows: 1. The working environment for building in the furnace is poor, the space is narrow, and the...

Problems solved by technology

[0003] The bottom block of the existing molten salt chlorination furnace is usually built and dried in the furnace, and its disadvantages are as follows: 1. The working environment of the furnace is poor, the space is narrow, and the efficiency of the building is low

2. The thickness of the masonry at the bottom of the molten salt chlorination furnace is large, and the design oven temperature in the furnace is only 300°. It is difficult to bake in the masonry furnace at the bottom to meet the requirements of design and use, and problems are prone to occur after being put into use

3. The masonry is thicker, and the method of masonry and baking in the furnace is prone to cracks and other quality defects during the baking process
