熱作模具鋼是指適宜于制作對模具進行熱變形加工的模具用的合金工具鋼，如熱鍛模、熱擠壓模、壓鑄模、熱鐓模等。由于熱作模具長時間處于高溫高壓條件下工作，因此，要求模具材料具有高的強度、硬度及熱穩定性，特別是應有高熱強性、熱疲勞性、韌性和耐磨性。下面來講講山東熱作模具鋼運用期間的功能。

Hot working die steel refers to alloy tool steel suitable for making dies for hot deformation processing, such as hot forging dies, hot extrusion dies, die-casting dies, hot upsetting dies, etc. Because the hot working die works under high temperature and high pressure for a long time, the die material is required to have high strength, hardness and thermal stability, especially high thermal strength, thermal fatigue, toughness and wear resistance. Let's talk about the functions of Shandong hot work die steel during its application.

熱作模具鋼的運用功用請錘鍛模具錘鍛模具作業時遭到很大的壓力和沖擊載荷效果，而且沖擊頻率很高，模具型腔外表遭到高溫模具的不時加熱，可使模具升溫到300℃~400℃，部分溫度抵達500℃~600℃。

The application function of hot work die steel is to use hammer forging die. The hammer forging die is subjected to great pressure and impact load effect during operation, and the impact frequency is very high. The surface of the die cavity is heated by the high-temperature die from time to time, which can make the die temperature rise to 300 ℃ ~ 400 ℃, and some temperatures reach 500 ℃ ~ 600 ℃.

錘鍛模具對模具鋼的功用請求是：具有較高硬度和很好的耐性；具有很好的耐磨性和耐冷熱疲憊性；由于模具尺寸比擬大，應具有很高的淬透性。熱擠壓模具熱擠壓模具的作業條件比擬差，一同承受緊縮力和彎曲力，脫模時還承受必定的拉應力，還遭到沖擊載荷的效果。

The functional requirements of hammer forging die for die steel are: high hardness and good resistance; It has good wear resistance and cold and hot fatigue resistance; Due to the large size of the mold, it should have high hardenability. Hot extrusion die the working conditions of hot extrusion die are relatively poor, and they bear tightening force and bending force together. When demoulding, they also bear certain tensile stress and impact load.

模具與高熱模具觸摸時辰較長，使其受熱溫度比錘鍛模具溫度更高。熱擠壓模具對模具鋼的功用請求是：具有較高的熱穩定性，有很好的抗冷熱疲憊強度，有較高的耐高溫強度和滿足的耐性。壓鑄模具壓鑄模具的失效方式有熱疲憊開裂、熱磨損和熱熔蝕。

The mold and the high-temperature mold touch for a long time, so that its heating temperature is higher than that of the hammer forging mold. The functional requirements of hot extrusion die for die steel are: high thermal stability, good cold and thermal fatigue strength, high temperature strength and satisfactory resistance. The failure modes of die-casting die include thermal fatigue cracking, thermal wear and thermal erosion.

壓鑄模具對模具鋼的功用請求是：具有較高的耐熱性和很好的高溫力學功用；具有很好的耐冷熱疲憊性和較高的導熱率；具有很好的抗氧化性和耐蝕性；具有較高的淬透性。凹模的硬度為56~60HRC,但請求耐性較高。

The functional requirements of die-casting die for die steel are: high heat resistance and good high-temperature mechanical function; It has good cold and heat fatigue resistance and high thermal conductivity; It has good oxidation resistance and corrosion resistance; It has high hardenability. The hardness of the female die is 56 ~ 60HRC, but it requires high resistance.

此外熱作模具在工作時承受著很大的沖擊力，模腔和高溫模具接觸，反復地加熱和冷卻，其使用條件其惡劣。為了滿足熱作模具的使用要求，熱作模具鋼應具備下列基本特性，較高的高溫強度和良好的韌性。熱作模具，尤其是熱鍛模，工作時承受很大的沖擊力，而且沖擊頻率很高，如果模具沒有高的強度和良好的韌性，就容易開裂。關注我們網站http://www.6886774.cn，了解更多內容！

In addition, the hot working die bears a great impact force when it is working. The die cavity contacts with the high-temperature die and repeatedly heats and cools. Its use conditions are very poor. In order to meet the use requirements of hot work die, hot work die steel should have the following basic characteristics: high high temperature strength and good toughness. Hot working dies, especially hot forging dies, bear a lot of impact force when working, and the impact frequency is very high. If the dies do not have high strength and good toughness, they are easy to crack. Follow our website http://www.6886774.cn Yes, learn more!
