Cast iron horizontal continuous casting double-water jacket type crystallizer

Abstract

The invention relates to a cast iron horizontal continuous casting double-water jacket type crystallizer, which comprises a double-water jacket type crystallizer steel sleeve and a high-purity graphite sleeve, wherein the high-purity graphite sleeve is embedded in the double-water jacket type crystallizer steel sleeve, the double-water jacket type crystallizer steel sleeve comprises a crystallizer steel sleeve inner sleeve and a crystallizer steel sleeve outer sleeve, the crystallizer steel sleeve outer sleeve is arranged at the exterior of the crystallizer steel sleeve outer sleeve, the crystallizer steel sleeve inner sleeve is provided with a spiral water passage with a trapezoidal cross section, a separating plate is arranged in the spiral water passage with the trapezoidal cross section, and is used for separating the spiral water passage with the trapezoidal cross section into a spiral water passage with a trapezoidal cross section I and a spiral water passage with a trapezoidal cross section II, the crystallizer steel sleeve outer sleeve is respectively welded with a water inlet pipe of a main sleeve A, a water outlet pipe of the main sleeve A, a water inlet pipe of an auxiliary sleeve A and a water outlet pipe of the auxiliary sleeve B, the water inlet pipe of the main sleeve A and the water outlet pipe of the main sleeve A are respectively communicated with the spiral water passage with the trapezoidal cross section I to form the main sleeve A, and the water inlet pipe of the auxiliary sleeve B and the water outlet pipe of the auxiliary sleeve B are respectively communicated with the spiral water passage with the trapezoidal cross section II to form the auxiliary sleeve B. The cast iron horizontal continuous casting double-water jacket type crystallizer has the advantages that the process advantages of horizontal continuous casting using separate control of the two water jackets are fully realized, the leakage of furnaces is avoided, the drawing speed is improved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of production equipment for horizontal continuous casting of cast iron, in particular to a double-water-jacketed crystallizer for horizontal continuous casting of cast iron. Background technique [0002] Cast iron horizontal continuous casting is a new technology for the production of modern high-quality cast iron blanks, and has been listed as a key promotion project of national scientific and technological achievements. "Cast Iron Horizontal Continuous Casting Technology" was identified as the 16th item in the 2003 Joint Announcement No. 23 of the State Environmental Protection Administration and the State Economic and Trade Commission [National Key Industry Clean Production Technology Guidance Catalogue], and was identified as a clean manufacturing technology project that is prioritized for development. Due to the incomparable advantages of continuous casting cast iron profiles in product quality, excelle...

AI Technical Summary

Problems solved by technology

[0005] At present, the method commonly used in the horizontal continuous casting of cast iron profiles is the spiral water channel with a rectangular cross-section of a single water jacket. unsatisfactory

At the same time, the length of the currently used mold is relatively short. For example, the length of the mold for producing Φ100mm cast iron profiles is only 250-300mm, and the length of the mold for Φ300mm cast iron profiles is only about 350-400mm.

The direct result of this short crystallizer is not only prone to furnace leaks, but also relatively low production efficiency. For example, the production capacity of Φ300mm cast iron profiles can hardly reach 20 tons per shift.
