立式淬火爐表面淬火只對(duì)工件的表面或部分表面進(jìn)行熱處理，所以只改變表層的組織,而心部或其它部分的組織仍保留原來的低硬度、高塑性和高韌性的性能. 這樣工件截面上由于組織不同性能也就不同。表面淬火便于實(shí)現(xiàn)機(jī)械化、 自動(dòng)化，質(zhì)量穩(wěn)定，變形小，熱處理周期短，費(fèi)用少，成本低。

立式淬火爐設(shè)備采用耐熱不銹鋼做風(fēng)道,料架采用高速起升,3～6秒內(nèi)進(jìn)水池.爐蓋電動(dòng)推桿升降,嚴(yán)格密封，使工件材料與外界空氣隔絕，在加熱、保溫過程中，爐內(nèi)有高強(qiáng)對(duì)流風(fēng)機(jī)，爐內(nèi)形成強(qiáng)對(duì)流循環(huán)，促使?fàn)t溫均勻，爐內(nèi)各點(diǎn)溫差可控制在1℃內(nèi)，從而使退火材料獲得均勻一致的物理機(jī)械性能。

Vertical Aluminium Alloy quenching furnace

Surface quenching of this type furnace only heat treat the surface or part surface of the workpiece , so only change the surface tissue, while the inside and other parts still retain the original low hardness, high plasticity and high toughness.

Surface quenching is easy to achieve mechanization and automation. It is stable quality, small deformation, short heat treatment cycle, less expenses and low cost.

Vertical quenching furnace uses heat - resistant stainless steel for air duct, material rack is raised at high speed, only need 3-6 seconds to get into water channel. In the process of heating and heat preservation, there is a high strength convection fan in the furnace, and a strong convection circulation is formed in the furnace, which makes the furnace temperature uniform. The temperature difference of each point in the furnace can be controlled within 1℃, so that the anneal material can obtain uniform physical and mechanical properties.
