Dome blowing is a technique used to form thermoplastic sheet material, (cast acrylic is ideal, max 10mm) into a hemispherical dome, without the use of a forming mould. Hence the often used term "free blown". The material is oven heated then placed on the flat bed of the equipment and clamped into position by a cast aluminum ring. Usually three different sizes are supplied. Using a compressor, air is then blown through perforations in the bed underneath the heated and ply-able acrylic to the required height usually the radius of the ring selected.
Cast iron is used as the "material of choice" for many machinery housings or bases because it is extremely stable in its structure. Certainly it is subject to thermal expansion and contraction, but the crystal structure of cast iron makes it "hold its shape" in applications ranging from machines and machine parts to cookware. And in things like a lathe bed, we need the thing to be "the same" every day and all the time so we get accurate, consistent work. Cast iron also suppresses high frequencies generated during machining. Note that the ways (the parts of the bed that the carriage slides on), are hardened and machined to provide lasting and accurate surfaces.
If the bed lamps use a low voltage bulb then the type of transformer will be a step down transformer.
In brinell scale ,the hardness value is 180
It is a kind of transformer used to make changes in accordance with the voltage connected to substituting current hardware. It associations are utilized as a part of a few places, for example, uninterruptible power supply units for PCs, and in the tanning bed industry....

Natural Cancained clay is used for making refractory bricks and shapes.But it find best and cheap use in the boiler of thermal power plants as a bed material. Because here it does not required any benification or calcination. you have to only to make grains (iron free) of required sizes which is directly used in the boiler of a thermal power plant as a bed material
