Embodiment Construction

[0031] The invention provides a square steel forging process. The square steel forging process includes the following steps:

[0032] 1) Prepare a square steel heating graph, the abscissa of the square steel heating graph is heating time, and the ordinate is heating temperature:

[0033] 1.1) Select different steel grades and obtain their own heating characteristics;

[0034] 1.2) Determine the furnace entry temperature, initial forging temperature and exit temperature of different steel grades according to the heating characteristics of different steel grades obtained in step 1.1);

[0035] 1.3) Determine the heating time of different steel grades during forging;

[0036] 1.4) Use the abscissa as the heating time and the ordinate as the heating temperature to draw the heating curves of different steel grades.

[0037] 2) Heat the square steel according to the square steel heating curve obtained in step 1):

[0038] 2.1) The furnace temperature is 50 degrees;

[0039] 2.2) Rapid heating up...

Abstract

The invention relates to a forging technology for square steel. The forging technology for the square steel comprises the following steps of 1), making a square steel heating curve graph, wherein the abscissa of the square steel heating curve graph represents the heating time and the ordinate of the square steel heating curve graph represents the heating temperature; 2), heating the square steel according to the square steel heating curve graph obtained in the step 1); and 3), performing upsetting and drawing-out treatment on the heated square steel. The forging technology for the square steel is high in technology precision and good in surface quality, and the casting technology is simple and reliable.

Description

Technical field [0001] The invention belongs to the field of metal forging and relates to a square steel forging process. Background technique [0002] In the forging process, forging can compact or weld the shrinkage cavity, shrinkage porosity, voids, bubbles and cracks in the as-cast metal structure, and can refine the grains and break the inclusions to obtain a certain forging flow Line organization. In actual production, various forgings are often used according to production needs, such as mainly used to produce various important and heavy-load machine parts or blanks, such as the main shaft and gears of machine tools, the connecting rods of internal combustion engines, the hooks of cranes, etc. In the process of processing, it needs to be deformed by upsetting, drawing, reaming, bending, drawing, etc. During the forging process, due to the oxidation and cooling shrinkage of the metal surface at high temperature, the precision of the forging is not high and the surface qual...
