Sičuanas Huitai Specialusis Plienas-Santrauka Iš Kalimas Technologija Specialioji Lydinys Plienas Kaltiniai dirbiniai

Specialus lydinys plienas kaltiniai yra daug daugiau sunku nei anglis struktūrinis plienas ir aukštas lydinys plienas. In order to gaminti specialus anglis plienas liejiniai kurių geometrinės specifikacijos ir metalurgijos pramonė kokybė atitiktis reikalavimai, atitinkamos tikslingos techninės atsakomosios priemonės must be taken pagal to skirtingos charakteristikos. Tokios atsakomosios priemonės įtraukti apdorojimas technologija atsakomosios priemonės, plienas liejiniai ir štampavimas štampavimas štampai atsakomosios priemonės, kokybė kontrolė priemonės aptikimas išlygų kalcinavimo charakteristikos (pagrįsta the selection of main thermal parameters) and simulation of the wholere calcination process, first sample trial forging, etc.

būtinas apdorojimas procesas atsakomosios priemonės yra aprašyta in stiprinimas priemonės paminėta žemiau:

1. Efektyviai pasirinkti parinkti temperatūra, šildymas greitis, izoliacija laikas žaliava medžiaga įėjimas krosnis

For specialus anglis plienas su žemas terminis laidumas (ypač a a keli coliai iš žaliavos medžiagos), the temperatūra turėtų būti pakeltas at mažas greitis in in krosnis arba šildomas ir izoliuotas for a periodas of time tarp 700 ir 900. It is not allowed to heat up immediately in the furnace at the initial forging temperature, and then raise the temperature to the initial forging temperature or to a high-temperature at the initial forging temperature at the initial forging temperature; The insulation time at the initial forging temperature depends on carbon steel and is paprastai soften times longer than alloy tool steel.
Other types of aluminum, magnesium, copper, and carbon steel with higher thermal conductivity than steel can be immediately heated in a high-temperature furnace, with an accelerated heating rate and a moderate reduction in insulation time.

2. Properly select the deformation level

3. Strictly control the final forging temperature

For the characteristics of high work hardening temperature and obvious strain hardening tendency of special carbon steel forgings, the final forging temperature must be increased or greatly increased. The final forging temperature of some carbon steels can even reach hg720, which is about 400 higher than the final forging temperature of carbon structural steels and high alloy steels.

4. Efficiently selecting the working speed of forging equipment

5. Effectively selecting forging equipment

For some special carbon steels with high deformation resistance, very slow work hardening and high final forging temperature, when compared with the same specification of broken indium and high alloy steel components, it is necessary to select those that can be seen or have a load 3 times larger? Forging equipment 5 times or larger.

6. Carry out safety protection for hair embryos

7. Conduct bi-directional wetting of hair germ and grinding tools

For the characteristics of special carbon steel, such as high deformation resistance, large kinetic energy (load) of necessary machinery and equipment, and narrow calcination temperature range, in addition to basic lubrication of grinding tools, safety protection lubrication of rough billets is also solved to avoid friction and temperature drop of rough billets as much as possible, in order to reduce the required tonnage of machine equipment. It is proposed to use laminated glass safety protection lubricant to carry out safety protection and lubrication for burrs during die forging of high-temperature alloy, titanium metal and stainless steel plates,

8. Try to select the technological process calcined under pressure crustal stress

9. 'Strike while the iron is hot'

For the charakteristikos of high final forging temperature and narrow calcination temperature range of special carbon steel, it is required that the forging worker is proficient in actual operation and agile in response. Every stage from the release of raw materials, transmission to calcination must be fast , striving to reduce calcination time as much as possible, pranokstantis the goal of "striking while the iron is hot".

10. Griežtai laikykitės iki the šildymas taisyklės ir reglamentai of special tools and grinding tools

For the charakteristikos of high final forging temperature, siauras kalcinavimas temperatūra diapazonas, ir žemas terminis laidumas of special anglis plienas, kurie yra jautrūs to šlifavimas įrankis gesinimas, visi užspaudimas ir šlifavimas įrankiai kad ateiti į kontaktą su plienas liejiniai must griežtai laikytis the reikalavimai šildymui.
