Mgbe ị na-anwale ike nke carbon steel gburugburu ogwe na ike siri ike, anyị kwesịrị ịhọrọ ihe nnwale ike nke ọma iji hụ na nsonaazụ ule ahụ ziri ezi ma dị irè. Anyị nwere ike ịtụle iji nha HRB nke ihe nnwale ike ike Rockwell.
Ihe nlere HRB nke Rockwell hardness tester na-eji ihe ntinye bọọlụ nchara nwere dayameta nke 1.588mm yana ikike nnwale dabara nke 100KG. A na-edobe nha nha nke nha HRB na 20-100HRB, nke dabara maka nnwale siri ike nke ọtụtụ ihe nchara carbon carbon gburugburu nwere ike dị ala.
1.Ọ bụrụ na agbanyụla ogwe osisi carbon steel ma nwee nnukwu ike nke ihe dịka HRC40 - HRC65, ị ga-ahọrọ ihe nnwale ike ike Rockwell. Ihe nnwale Rockwell hardness dị mfe na ngwa ngwa ịrụ ọrụ, ma nwee ike gụọ uru hardness bara uru ozugbo, nke dabara maka ịlele ihe ndị siri ike dị elu.
2.N'ihi na ụfọdụ carbon ígwè gburugburu Ogwe ndị e mesoro na carburizing, nitriding, wdg, elu ike dị elu na isi ike dị ala. Mgbe ọ dị mkpa iji tụọ ike nke elu ya nke ọma, enwere ike ịhọrọ onye na-anwale ike ike Vickers ma ọ bụ onye nyocha microhardness. Ntinye nke ule siri ike nke Vickers bụ square, yana uru ike siri ike ka a na-agbakọ site na ịlele ogologo diagonal. Ogo nha nha dị elu ma nwee ike gosipụta n'ụzọ ziri ezi mgbanwe ike siri ike n'elu ihe.
3.In mgbakwunye na HRB ọnụ ọgụgụ nke Rockwell hardness tester, Brinell hardness tester nwekwara ike iji nwalee ala-ike carbon ígwè gburugburu mmanya ihe. Mgbe a na-anwale carbon steel gburugburu ogwe, onye ntinye ya ga-ahapụ nnukwu ebe ntinye n'elu ihe ahụ, nke nwere ike igosi n'ụzọ zuru ezu na n'ụzọ zuru ezu na-egosipụta nkezi ike nke ihe ahụ. N'oge a na-arụ ọrụ nke ihe nleba anya siri ike, onye na-anwale ike ike Brinell adịghị ngwa ngwa ma dị mfe dịka onye na-anwale hardness hardness nke Rockwell. Ihe nnwale ike ike Brinell bụ ọnụ ọgụgụ HBW, na indenters dị iche iche dabara na ike nnwale. Maka ogwe osisi carbon steel nke nwere ike siri ike n'ozuzu ya, dị ka ndị nọ na steeti annealed, ike siri ike na-adịkarị gburugburu HB100 – HB200, enwere ike họrọ onye nyocha Brinell hardness tester.
4.For carbon ígwè gburugburu ogwe na nnukwu dayameta na mgbe udi, dị iche iche hardness testers bụ n'ozuzu na ọdabara. Agbanyeghị, ọ bụrụ na dayameta nke ogwe okirikiri dị obere, dị ka ihe na-erughị 10mm, ihe nnwale ike ike Brinell nwere ike imetụta nha nha n'ihi nnukwu ntinye. N'oge a, enwere ike ịhọrọ onye nnwale ike ike Rockwell ma ọ bụ Vickers hardness tester. Ogo ihe ntinye ha pere mpe ma nwee ike tụọ nke ọma ike nke ihe nlele pere mpe.
5.For irregularly ekara carbon ígwè gburugburu ogwe ndị siri ike na-etinye na workbench nke a ot hardness tester maka nha, a obere ike ike tester, dị ka a Leeb hardness tester, nwere ike họrọ. Ọ na-eji ngwaọrụ mmetụta na-eziga ahụ mmetụta n'elu ihe a na-atụ, ma gbakọọ uru ike siri ike dabere na ọsọ nke mmetụta ahụ na-alaghachi. Ọ dị mfe iji rụọ ọrụ ma nwee ike ịrụ nha na saịtị na workpieces nke ụdị na nha dị iche iche.
