Factory Price Graphite Mold Graphite Crystallizer for Copper Brass Continuous Casting

A slurry circulating continuous crystallizer (Figure 1). During operation, the material liquid is added from the lower part of the circulation tube, mixed with the crystal slurry leaving the bottom of the crystallization chamber, and then pumped to the heating chamber. The crystal slurry heats up in the heating chamber (usually 2-6 ℃), but does not evaporate. After the hot crystal slurry enters the crystallization chamber, it boils, causing the solution to reach a supersaturated state. As a result, some solutes deposit on the surface of suspended grains, causing the crystals to grow. As a product, the crystal slurry is discharged from the upper part of the circulation pipe. The forced circulation evaporation crystallizer has a large production capacity, but the particle size distribution of the product is relatively wide.

There are two types of crystallizers according to the linear division of the inner wall of the section in the direction of casting: curved and straight; According to its overall structure, there are both sleeve and combination types for both curved and straight shapes.

The cooling water jacket composed of inner wall copper pipes, inner and outer water jackets, and foot rollers are its main components. The outer surface of straight or curved copper pipes consists of cooling water jackets, flanges, and sealing elements, forming a water supply and oil supply system. In order to ensure a regular appearance of the billet, 2-3 sets of foot rollers are installed at the bottom of the mold to improve the casting speed and prevent the billet from falling off square.
