3. Nka na ụzụ chọrọ maka akụrụngwa quenching na tempering:

1) Ngwunye elu elu nke ogwe aka dum bụ 22-27 degrees HRC , ike kachasị ike enweghị ike ịbụ ihe na-erughị ogo 22, na ike kwesịrị ekwesị bụ ogo 24-26;

2) Ịdị ike nke otu ogwe ahụ ga-abụrịrị otu, ike nke otu ihe ahụ ga-abụkwa otu, na ịdị n’otu nke ogwe ahụ ga-adị n’ime ogo 2-4.

3) Nzukọ ahụ ga-abụrịrị otu na akụrụngwa akụrụngwa na-emezu ihe achọrọ:

a. Ike mpụtara karịrị 50kgf/mm ²

b. Ike tensile karịrị 70kgf/mm ²

c. Elongation karịrị 17%

4) Ebe kachasị ala nke etiti gburugburu agaghị adị ala karịa HRC18, ebe kachasị ala nke 1 / 2R agaghị adị ala karịa ogo HRC20, na ebe kachasị ala nke 1 / 4R agaghị adị ala karịa HRC22 degrees.

2. Workpiece nkọwa

Dị ka ihe ndị na-azụ ahịa chọrọ, anyị na-enye ndị na-esonụ tent nke sensọ maka 45-150 gburugburu ígwè.

Dabere na tebụl nkọwapụta workpiece nyere onye zụrụ ya, achọrọ ngụkọta nke 4 nke inductors, 4 setịpụrụ nke ọ bụla maka imenyụ na iwe ọkụ. The kpo oku nso nke workpiece bụ 40-150mm. Ihe mmetụta okpomọkụ na-ekpo ọkụ na-anabata 800mm × 2 imewe, ihe ọkụ ọkụ na-ekpo ọkụ na-ekpo ọkụ na-ejikọta 800mm × 1 imewe, na onye na-echekwa okpomọkụ na-ekpo ọkụ na-anabata 800mm × 1 imewe iji hụ na kpo oku otu. A na-emepụta akụkụ iwe ọkụ n’otu ụzọ ahụ.

Atọ, nkọwa nhazi usoro

Nke mbụ, jiri aka tinye ihe ndị na-arụ ọrụ nke dị mkpa ka a kpoo ọkụ n’otu ahịrị na otu oyi akwa na nchekwa nchekwa nri, mgbe ahụ, a na-eji nwayọọ nwayọọ na-eziga ihe ndị ahụ na-edozi ahụ site na igwe na-ebu ibu, mgbe ahụ, a na-agbanye ihe ahụ n’ime nri. rola nwere mmasị site na cylinder ikuku. Rola nke nwere mmasị na-ebugharị ihe mmanya ahụ gaa n’ihu wee ziga ihe ahụ na inductor kpo oku. Mgbe ahụ, workpiece na-ekpo ọkụ site quenching kpo oku akụkụ, na quenching kpo oku na-ekewa n’ime quenching kpo oku kpo oku na quenching okpomọkụ ichebe kpo oku. N’ebe a na-emenyụ ọkụ na ikpo ọkụ, a na-eji ọkụ eletrik dị n’etiti 400Kw na-ekpo ọkụ na-arụ ọrụ, mgbe ahụ, a na-eji usoro abụọ nke 200Kw ike ọkụ na-ekpo ọkụ maka nchekwa ọkụ na kpo oku.

Mgbe kpo oku na-agwụ agwụ, na workpiece na-chụpụrụ site na mmasị roller ịgafe quenching mmiri ịgba mgbanaka maka quenching. Mgbe quenching dechara, ọ na-abanye na tempering kpo oku inductor maka tempering kpo oku. A na-ekewakwa ikpo ọkụ ọkụ na akụkụ abụọ: okpomọkụ okpomọkụ na nchekwa okpomọkụ. Akụkụ kpo oku na-eji ọkụ ọkụ etiti 250Kw, na akụkụ nchekwa ọkụ na-eji usoro abụọ nke 125Kw ike ugboro ugboro. Mgbe kpochara ọkụ ahụ, a na-ewepụ ihe ahụ, a na-eme usoro ọzọ.
