Copper Cold Hearth for Electron Beam Melting (EB)

Cold hearth, copper cooling bed and overflow clip for Furnace EBCHM,EBCHR,PACHM —HZC successfully produced the copper cold hearth core parts of ALD EBCHR furnace, and optimized design of water channels. HZC produced the cooling bed and overflow clip by forging and machining process. Material is pure copper 99.9% . The cold hearth is mainly used for EBCHR, EBCHM, PACHM Furnace to remelting and refining refractory and reactive metals and alloys. EB furnace is mainly employed for the production of refractory and reactive metals (tantalum, niobium, molybdenum, tungsten, vanadium, hafnium, zirconium, titanium) and their alloys.

Electron beam melting is distinguished by its superior refining capacity and offers a high degree of flexibility of the heat source. Thus, it is ideal for remelting and refining of metals and alloys under high vacuum in water-cooled copper molds. Today the process is mainly employed for the production of refractory and reactive metals (tantalum, niobium, molybdenum, tungsten, vanadium, hafnium, zirconium, titanium) and their alloys. It plays an important role in manufacturing of ultra-pure sputtering target materials and electronic alloys and the recycling of titanium scrap.
Electron Beam Cold Hearth Refining (EBCHR)
is of great importance for processing and recycling of reactive metals. The feedstock is drip-melted in the rear part of a watercooled copper hearth from where it overflows into the withdrawal mold. During the dwell time of the molten material in the hearth system gravity separation of highand low-density inclusions (HDI, LDI) can be achieved in addition to the refining mechanisms described above. The hearth must be properly sized to provide sufficient dwell time of the molten metal in the hearth in order to permit efficient gravity separation of HDIs and LDIs. Larger hearth melting systems are equipped with a larger number of EB guns to provide the required power and energy distribution.

1. Electron beam drip-melting of tantalum, 2. EB cold hearth refining, 3. Electron beam floating zone melting

EB Cold Hearth Production Furnaces
for production of reactive metal ingots and slabs, including material recycling. Ingot weights up to 15 tons, total beam power above 3 MW with up to 6 guns.

Forged Copper pressure rings and contact clamps for submerged arc furnace

HZC solutios produce Forged Copper pressure rings and contact clamps for submerged arc furnace
Submerged arc furnaces are mainly used for the production of ferroalloys.
Additionally, the units produce calcium carbide (CaC2) and calcium silicon (CaSi) for secondary metallurgy in steel production. And finally, this technology is ideal for reprocessing / recycling residues from the iron and steel industry. Here is an overview of the main applications:

Ferro silicon (incl. FeSi45, FeSi75, FeSi90)
Ferro manganese (incl. H.C. FeMn, M.C. FeMn, L.C. FeMn, M.C. SiMn)
Ferro chromium (incl. H.C. FeCr, M.C. FeCr, L.C. FeCr, SiCr)
Ferro nickel (incl. 15 – 30% Ni)
Special alloys (incl. FeV, FeNb, FeW, FeMo)
CaC2, CaSi
Raw materials for the refractory industry (incl. corundum, smelting magnesia, mineral wool)
Metallurgical plant residue reprocessing and recycling (incl. flue dust, scale, slag, salamanders)

Copper cooler stave for blast furnace

HZC copper stave technology is one of the products of such efforts.Cooler stave is a cooling device having one or more internal water channel, and is installed in numbers on the inner surface of a blast furnace to protect its steel shell and maintain the inner profile. HZC staves were made by forging,drilling and machining process. HZC blast furnace copper cooling staves’ working life is five to six times longer than by casting process. We choose cold rolled sheet as material and then deep hole drilling, welding, welds inspection, pressure and ultrasonic test.
