6 FAQs about [Energy storage welding with lots of slag]
What is the energy content of slag?
Energy content of slags The energy consumed in high temperature processing of metals is distributed between metal, slag, off-gas, and the natural losses to the atmosphere. The slag thermal energy represents about 10–90% of the output energy depending on the slag/metal ratio and the discharge temperature.
Is slag a potential heat storage material?
In this paper, the microstructures, thermal properties, wear resulted from the heat expansion and cold contraction of the slag with storaging and releasing process of two EAF slag samples were addressed. The results revealed that slag is a potential heat storage material.
Why is slag a problem in gas metal arc welding?
As such, the application of advanced high-strength steels is rapidly increasing. However, in the case of gas metal arc (GMA) welding of advanced high-strength steels (AHSS), slag particles are observed to form on the weld surface resulting in poor corrosion resistance. The presence of slag particles on the weld also affects mechanical performance.
How much slag can be produced if cooled to 150 °C?
This slag, if cooled to 150 °C through the proposed system, can generate as much as 106 Nm 3 of CO + H 2 (molar ratio of H 2:CO = 3:1) exiting the reactor at 1100 °C. This would represent chemical energy recovery of 0.24 GJ/ton crude steel (0.81 GJ/ton slag) or 51% of the slag thermal energy.
Does electric arc furnace slag meet a high temperature environment?
In this paper, the thermal stability, specific heat capacity, thermal conductivity and microstructures of two electric arc furnace (EAF) slag samples were studied. In TES system, as heat storage material, slag will meet with high temperature and low temperature environment.
Where does slag flow in a weld arc?
The slag moved from the low surface tension region (lower temperature at the outer edge of the weld pool) to the high surface tension region, which is at a higher temperature under the welding arc. In this case, molten metal will flow from the weld periphery towards the center of the weld pool, creating an inward flow pattern, as shown in Fig. 3e.
