Abstract
The invention relates to a forging process for a template. The forging process comprises the following steps: (1) heating a steel ingot to 810-830 DEG C with first fire, and chamfering, wherein the first fire heating speed is 40-45 DEG C per house; (2) heating a blank obtained in the step (1) once again to 1,090-1,110 DEG C with second fire, upsetting the steel ingot, and flattening rotationally; (3) heating a blank obtained in the step (2) once again to 1,060-1,090 DEG C with third fire, forging to a required specification, annealing: slowly cooling to 800-900 DEG C, and quenching: cooling in oil of 1,050-1,100 DEG C. Products produced with the process are uniform in internal composition, have good continuity, compactness and long service lives, and are prevented from cracking.
Description
Technical field
The invention belongs to technical field of forging, particularly relate to a kind of forging process of bulking machine template.
Background technology
Template is the key part of bulking machine, and ordinary material under pressure, directionally by a template, is made finished product continuously shapedly, is called as extruding.Template is because of easy to wear the opening that be squeezed for a long time, and adopt forging to increase wear resistance at present at home, but the forging process of routine easily causes distribution of carbides uneven, coarse grains is easy to crack.
Summary of the invention
Object of the present invention, in order to solve the problems of the technologies described above, provides a kind of forging process of template, and this technique, by improving ingot composition and forging process improves forging inner quality, crystal grain thinning, eliminates ununiformity.Its technical scheme is as follows: a kind of forging process of template, it is characterized in that, described template is made up of following component by weight percentage: c: 0.36 ~ 0.45 si :≤0.60 mn :≤0.80 p :≤0.035 s :≤0.030 ni :≤0.60 cr: 12.00 ~ 14.00, and surplus is Fe; Described forging process comprises the steps: 1) the first fire will have Heating Steel Ingots temperature to 810 ~ 830 DEG C of above-mentioned composition, chamfered edge, the first fiery heat-up rate 40 ~ 45 DEG C/h; 2) the second fire is to 1) step obtain base material again heat, be heated to 1090 ~ 1110 DEG C, then to steel ingot jumping-up, rotate flatten; 3) the 3rd fire is to 2) step obtain base material again heat, be heated to 1060 ~ 1090 DEG C, after the specification required for forging, annealing: 800 ~ 900 DEG C of slow cooling, quenching: 1050 ~ 1100 DEG C of oil coolings.
Compared with prior art, advantage of the present invention is: the inherent homogeneous microstructure of product, has good continuity and compactness, not easy to crack, long service life.
