Macrotype metal mold system for recovering thermal energy by cooling water

Abstract

The invention discloses a large water cooling heat recovery metal pattern system, belonging to the field of water cooling heat recovery in the casting technology of a plurality of castings such as large steel ingots and rollers. The invention adopts the technical proposal in comprising a metal pattern, the upper part of which are fixed with an electric heating riser and a metal pattern chassis; a cooling pipe is arranged inside the metal pattern, and a water inlet tube head and a water outlet tube head respectively communicated with the water inlet and outlet of the cooling pipe are arranged on the external surface of the metal pattern; a cooling pipe is arranged inside the metal pattern chassis, and a water inlet tube head and a water outlet tube head respectively communicated with the water inlet and outlet of the cooling pipe are arranged on an external surface of the metal pattern chassis. The invention has the advantages of long service life, high quality of casting pieces, good heat recovery and environment protection, and wide application prospect.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to the water-cooled heat energy recovery technology in the large steel ingot or roll casting technology. Background technique [0002] The existing metal mold casting technology is divided into two categories, one is the traditional metal mold steel ingot mold casting technology, and the other is the continuous casting technology of water-cooled copper crystallizer. The traditional metal-shaped steel ingot mold casting technology appeared earlier. With the continuous maturity of the water-cooled copper crystallizer continuous casting technology, almost 80% of the metal-shaped steel ingot production is replaced by continuous casting ingots. Since the continuous casting ingot technology is suitable for mass production of the same specification conditions, and the existing technology is limited to square billets, rectangular billets, cylindrical billets, etc. with small cross-sectio...

AI Technical Summary

Problems solved by technology

These two methods have the following problems: one, the cooling effect is poor, and the effective cooling control requirements for different parts of the steel ingot at different times cannot be realized, so there is no beneficial effect on the product quality, so the quality assurance of the produced product is poor; The loss of heat and hot water vapor into the air causes serious environmental pollution, especially in summer, causing the ambient temperature to be very high; third, heat energy cannot be recycled
