Kedu otu esi ahọrọ ihe nleba anya ike maka ịnwale sample tubular?

1) Enwere ike iji ihe nnwale Rockwell hardness tester nwalee ike nke mgbidi ọkpọkọ ígwè?

Nnwale ihe bụ SA-213M T22 ígwè ọkpọkọ na elu dayameta nke 16mm na a mgbidi ọkpụrụkpụ nke 1.65mm. Nnwale ule nke Rockwell hardness test bụ ndị a: Mgbe ewepụchara oxide scale na decarburization oyi akwa n'elu sample na grinder, a na-etinye sample na V- workbench, na HRS-150S digital Rockwell hardness tester na-eji na-anwale ozugbo Rockwell hardness n'elu elu ya na ibu nke 980.7N. Mgbe ule ahụ gasịrị, enwere ike ịhụ na mgbidi ọkpọkọ nchara nwere ntakịrị nrụrụ, nsonaazụ ya bụ na uru Rockwell hardness a tụrụ dị oke ala, na-ebute ule na-adịghị mma.

Dị ka GB/T 230.1-2018 «Metallic Materials Rockwell Hardness Test Part 1: Test Method», Rockwell hardness bụ 80HRBW na kacha nta sample ọkpụrụkpụ bụ 1.5mm. The ọkpụrụkpụ nke sample No. 1 bụ 1.65mm, ọkpụrụkpụ nke decarburized oyi akwa bụ 0.15 ~ 0.20mm, na ọkpụrụkpụ nke sample mgbe wepụ decarburized oyi akwa bụ 1.4 ~ 1.45mm, nke dị nso na kacha nta ọkpụrụkpụ nke sample kpọmkwem na GB / T 230.1-2018. N'oge ule ahụ, ebe ọ bụ na ọ dịghị nkwado dị n'etiti etiti ihe nlele ahụ, ọ ga-eme ka ọ dị ntakịrị nrụrụ (nke anya gba ọtọ agaghị ahụ ya), ya mere n'ezie uru hardness Rockwell dị ala.

2) Olee otú họrọ elu hardness tester maka ígwè ọkpọkọ:

Mgbe ọtụtụ ule na elu ike nke ọkpọkọ ígwè, ụlọ ọrụ anyị abịawo ná nkwubi okwu ndị a:

1. Mgbe ị na-eduzi ule Rockwell hardness test ma ọ bụ Rockwell hardness test n'elu ọkpọkọ ígwè dị mkpa, nkwado na-ezughị ezu nke mgbidi ọkpọkọ ga-eme ka nrụrụ nke ihe atụ ahụ pụta ma na-eduga na nsonaazụ ule dị ala;

2. Ọ bụrụ na agbakwunyere nkwado cylindrical n'etiti ọkpọkọ ígwè dị mkpa, nsonaazụ ule ga-adị ala n'ihi na axis nke isi nrụgide na ntụziaka nke ibu ibu enweghị ike ijide n'aka na ọ ga-adaba na elu nke ọkpọkọ ígwè, na e nwere ọdịiche dị n'etiti elu elu nke ọkpọkọ ígwè na nkwado cylindrical dabara adaba.

3. Usoro nke ịtụgharị siri ike Vickers tụrụ atụ na Rockwell hardness mgbe etinyere na ihicha ihe nlele igwe nchara bụ ihe ziri ezi.

4. Mgbe o wepụsịrị ọnụ ọgụgụ oxide na decarburization oyi akwa n'elu nke ígwè ọkpọkọ na machining ule ụgbọelu na n'elu elu na inlaying ya, elu Rockwell hardness na-atụgharị na Rockwell hardness, bụ nke ziri ezi.
