iron is collected from blast furnace by drilling the taphole.Taphole is a hole drill and plug after cycle of time located in blast furnace bottom.
High alumina fire bricks are commonly used in applications involving molten blast furnace slag due to their high refractoriness and resistance to thermal shock. These bricks are able to withstand the high temperatures and harsh conditions of the slag without deforming or deteriorating quickly.
The two liquids tapped off from a blast furnace are molten iron and slag. Molten iron is the main product, while slag is a byproduct that is formed from impurities in the ore.
Slag is the waste which is skimmed off the top of the molten iron that comes out of the blast furnace. It is a mixture of calcium and magnesium compounds, plus other impurities such as iron oxide, but is mainly calcium silicate. The formula for calcium silicate is CaSiO3.
The middle region of the blast furnace is called the bosh. It is where most of the chemical reactions, such as the reduction of iron ore and the formation of slag, take place. The bosh is a critical part of the furnace for producing molten iron efficiently.

The viscosity of slag in a blast furnace typically ranges from 1 to 10 Pa.s (Pascal-seconds) at typical operating temperatures. Viscosity can vary based on factors such as temperature, composition of the slag, and other process conditions within the blast furnace.

This is a mixture not a compound.
The main products of a blast furnace are pig iron (used to make steel) and slag (a byproduct that is used in construction materials).

because in a blast furnace the limestone removes unwanted substances as slag.

Slag from a blast furnace is usually ground down and used as a cement substitute as it is re-use of a waste product - it is not used on its own in concrete as the chemical reaction will not produce the same strength as proper cement.
Slag is intentionally placed above the layer of iron in a blast furnace to create a protective barrier. The slag layer acts as insulation, preventing the molten iron from exposure to the air and preventing oxidation. This helps maintain the temperature needed for the iron to be extracted from the ores.
