Manufacturer of high quality silica ramming mass and quartz powder and having high pourity quartz upto 99.8% silica and will manufacture the product as per the requirement of customer

The ramming material is generally hygroscopic in nature. When ramming is done care should be taken not to open all the bags of ramming material simultaneously. Two or three bags should be open at a time. All the material should be mixed together. Moving a magnet in the material will remove the possibility of any magnetic material in the mass. The material should be heated to around 60 to 70C to remove moisture.
The furnace is now made ready for ramming. The ground leak detector probe is placed in position with bottom asbestos sheet. The probe wire should be so arranged that all the lead should be inside the former diameter pointing vertically upwards approximately circularly spaced. The furnace coil coating is also sheed with asbestos sheet (one or two pc. ) It should be remembered that the ends of asbestos sheet should overlap each other. Asbestos paste should be made and applied over the lap joint so that the sheet remains in position, alternatively, spring tension ring can be used. With this ring care must be taken not to move the sheets while changing the position of the ring.
Put the ramming mass in the furnace tow or three inch level. Use spike rammer for 5 to 7 minutes and then use flat rammer for 10 minutes check if the level has gone down to around 1 to 1.5". Scrap the surface and put some more ramming mass again checking the level to 2 to 3". Repeat the operation till the required level is reached. Always go approx.5" more and scrap to desired thickness of the bottom. This will ensure flat even bottom ramming. In doing the bottom ramming take care of the GLD. All the leads should be seen out of the ramming. The ramming should give ringing sound in last then only the second charge should be given.
Now take the melt out former. Clean it from outside for rust and dirt, place it inside the furnace. Care should be taken that the former is placed concentric to the bottom i. E. Equal distance from all the periphery should be maintained to level equal side thickness of ramming. Place sufficient weight in the former so that it will not get displaced while ramming.
Take the spike rammer; poke the side of bottom ramming little bit so as to take the bottom and side homogeneous. Put ramming mass to get a level of three to four inches. Two people should start ramming diametrically opposite using spike rammer. Those people should keep moving round, so that equal ramming force is maintained. Ramming should be continued for 30mm...
Put another round of ramming mass. Continue the operation till first step of syndanco sheet is reached. Now use flat rammer and ramming should be done for five minutes. Alternatively put ramming mass to go above the first step, and then scrap it out to first step. Take care not to form layers. Layers may lead to puncture as metal can penetrate through the layers.
To make the top-cop and pour spout, mix the same ramming mass with sodium silicate. The mixture should be such that when made a ball it should retail its shape, but if more pressure is applied, it should disintegrate. Put little sodium silicate on the rammed portion - and then put this wet ramming mass. Complete the top-cop and the pour spout. Take 1/8 rod around12" length. Push it through the top-cap vertically at several places to make holes as deep as possible reaching to dry ramming. Do not move the rod side-ways, that will deteriorate the top-cap. These holes are required to give way for moisture.
With this the furnace is ready for sintering. Do not tilt the furnace with raw unsustained lining. This can given rise to cracks and may end in coil puncture.
