Dry Type Ramming Material for Electric Furnace Hearth Refractory Material DM-1
Construction Method
1. When the hearth permanent liner and furnace wall of the electric furnace are built, clean it, and foreign matter is forbidden. Then add dry type ramming material. The paving thickness of material each time is about 150mm. Apply vibrator to vibrate or apply compactor to tamp and apply air hammer tamping to newly built furnace hearth. In this way, not only the density of masonry is enhanced, but also the taking of fine dust reduction measures is facilitated. That is, when the ramming material of each layer is added, lay flax (or canvas), then carry out ramming. The method of ramming is to ram from circumference to center in clockwise according to concentric circle method each time, and each ramming is increased, and then to ram from center to circumference. Repeatedly Repeat the process is for about three times. Mould shall be set up at slope position and rammed to required thickness according to the above method. After the construction, it would be better not to remove the mould used for slope.
2. When the furnace hearth is rammed, cover the surface of the dry type ramming material with scrap steel plate with a thickness of about 3mm (if the mould for slope is not removed, only the exposed surface of dry type ramming layer is covered), so as to prevent the furnace hearth from being damaged when applying initial furnace burden.
3. In the beginning of smelting (especially the first 5-10 furnaces), lime shall be added first and then balk material is added, then heavy material is added. Reduce the height of material adding as much as possible, properly enhance the smelting temperature and extend smelting period, so as to make sure that enough sintering layer is formed at furnace hearth.
4. Pay attention to observing the situation of furnace. When the iron runs from each furnace, use a rake to probe furnace hearth. At the same time, pay special attention to the corrosion situation of furnace slope and carry out maintenance.
5. In case of pitting or local deterioration in furnace hearth or furnace slope, repair measures shall be taken. The original furnace hearth ramming material is applied as repairing mass.

Dry Type Ramming Material for Electric Furnace Hearth Refractory Material DM-1
The product is produced with high quality composite raw material and multi-element composite additive and agglutinant. It has characteristics of excellent capacity of liquid iron and slag corrosion and flushing resistance, compact sintered layer, long service life, low ton iron consumption, easy construction and repair, energy conservation. The product is applicable to UHP furnace hearth and furnace slope work liner.
Since the furnace hearth and furnace slope encounter the corrosion and flushing of high temperature liquid iron and slag and the mechanical flushing when adding scrap steel, refractory with excellent high temperature performances such as corrosion resistance, flushing resistance and thermal shock resistance etc. should be selected. The product has excellent sintering character to form hard compact layer and excellent high temperature structure strength to guarantee security and reliability during the process of using. Meanwhile, the content of magnesia oxide in base material is enhanced properly to improve the capacity of resisting the corrosion of ferric oxide. Compared with dry type ramming material with high calcium oxide content (18-20%), the sintering transition layer is thinner, so the heat loss of furnace hearth is lower.
