[0002] When producing φ130-170mm steel rods, 2.1t ingots are conventionally used for production. During the production, it was found that the 2.1t ingots need to go through two fires when they are forged by a 1300t precision forging machine, and the quality of the core is not very stable, and cracks are prone to appear in the core. Or loose voids, and the production process is complex, time-consuming and inefficient

Abstract
The invention discloses a steel ingot mould, and relates to the technical field of metallurgy. The steel ingot mould is characterized in that lifting lugs are symmetrically arranged on two side wallsof the upper end and the lower end of a shell; a cavity is formed in the shell, the cavity is integrally conical, the longitudinal section of the cavity is in a trapezoid shape, and the cross sectionof the cavity is in a regular octagon shape; and the height of the trapezoid is 1365 mm, an upper opening of the octagon is externally connected to a circle with the Phi of 500 mm, a lower opening ofthe octagon is externally connected to a circle with the Phi of 445 mm, and the taper of the upper opening of the octagon and the lower opening of the octagon is 1.56 degree. According to the steel ingot mould, the product quality can be improved, and the deformation forging ratio of the material can be improved to the maximum extent, the quality of the steel ingot is improved, the micro-structurequality is improved, and the raw materials can be saved.
Description
technical field [0001] The invention relates to a steel ingot mold, which belongs to the technical field of metallurgy. Background technique [0002] When producing φ130-170mm steel rods, 2.1t ingots are conventionally used for production. During the production, it was found that the 2.1t ingots need to go through two fires when they are forged by a 1300t precision forging machine, and the quality of the core is not very stable, and cracks are prone to appear in the core. Or loose cavity phenomenon, and the process is complicated during production, wastes time, and efficiency is low. Contents of the invention [0003] In view of the above problems, the technical problem to be solved by the present invention is to provide a steel ingot mold. [0004] A steel ingot mold according to the present invention comprises a shell and lifting lugs; lifting lugs are symmetrically installed on the two side walls of the upper and lower ends of the shell, and a cavity is arranged inside...
