INSURAL refractory materials are pre-formed insulating refractory materials with excellent properties, non-stick aluminum; no asbestos; durable and its structure is elastic; can be cut, drilled and machined; small shrinkage rate, high surface strength, no chemical reaction with aluminum, avoiding inclusions, easy to remove the aluminum shell, density can be controlled, low heat capacity. Life is 12 months. PT-190 castable is an extremely dense, alumina-based refractory material. SC-2600 castable is a high-purity silicon carbide-based refractory material with high thermal conductivity and stable performance at high temperatures. AR castable is a molten silica refractory material specially formulated to resist aluminum liquid thermal shock.

This manual is an operator's guide for the SINUMERIK 840D/840Di/810D control system, which introduces all the main programming steps. Its purpose is to provide the operator with some quick help and help with memory, especially some uncommon commands, or to provide a quick reference to various parameters.
