ʻO ka HP graphite electrode ka nui o ka petroleum coke, ka nila coke e like me ka mea maka, ka lanahu e like me ka mea hoʻopaʻa, ma hope o ka calcination, nā meaʻai, ke kāwili ʻana, ke kaomi ʻana, ka ʻala, ka graphitization, ka mīkini a hana ʻia. a me graphite electrodes hp me ka oxidation kū'ē, haʻahaʻa resistivity, kaʻakika a me ka alkali corrosion, kiʻekiʻe ka pono a me ka ikehu hoola, haʻahaʻa poho a me kekahi mau ano.

Hiki ke hoʻohana nui ʻia nā graphite electrodes hp i ka umu hoʻoheheʻe uila no ka hana ʻana i ka ferroalloy, silika maʻemaʻe, phosphorus melemele, copper matte, calcium carbide a pēlā aku.
Hiki ke hoʻohana nui ʻia nā electrodes HP Graphite i ka umu hoʻoheheʻe uila no ka hoʻoheheʻe ʻana i ke aniani, ka hana carbide silika, ka hana huahana graphite.
ʻO ka hale hana refractory ʻo RS kahi mea hoʻolako HP Graphite electrodes hp i hoʻokumu ʻia i nā makahiki 90 o iwakālua mau kenekulia.
