For foundry and metallurgical enterprises that rely on medium‑frequency coreless induction furnaces for metal melting, furnace lining performance is one of the key factors restricting production safety, product quality and comprehensive operating cost. Many manufacturers have encountered common troubles such as lining early cracking, molten metal penetration, slag erosion and short service campaign when using traditional acidic or alkaline ramming mixes. In order to solve these practical pain points in actual smelting production, Gaoyou Fangyuan Furnace Material Factory has completed formula iteration and mass production of FYAC‑90CR Neutral Ramming Material, bringing a dependable neutral refractory solution for global foundry customers.
FYAC‑90CR Neutral Ramming Material belongs to dry‑type neutral ramming refractory specially developed for induction furnace working conditions. It adopts high‑purity neutral refractory aggregate with scientific particle gradation, cooperating with multi‑component functional additives. Different from acid silica‑based ramming mass and alkaline magnesia‑series ramming materials, this neutral ramming mix keeps good chemical inertness under high‑temperature environment. It will not produce violent chemical reaction no matter contacting acid slag or alkaline slag generated in steel, iron and alloy smelting process, so it can effectively slow down lining erosion and peeling caused by chemical corrosion.
In construction aspect, FYAC‑90CR Neutral Ramming Material is suitable for both manual ramming and pneumatic mechanical ramming operations. After sufficient layered ramming compaction, it will form low‑porosity and high‑density integral furnace crucible lining. During the furnace baking and later repeated high‑temperature thermal cycles, the material shows excellent high‑temperature volume stability, with low permanent linear change rate, hardly producing excessive expansion or severe shrinkage. Such property greatly reduces the risk of structural crack generation. Its good thermal‑shock resistance enables the lining to withstand frequent sharp temperature rise and fall in induction furnace melting work, avoiding lining spalling failure.
Slag resistance performance is another core highlight of FYAC‑90CR Neutral Ramming Material. Compact sintered layer can block slag penetration, prevent molten steel and molten alloy permeating into the interior of refractory lining, so as to protect induction furnace coil and other key components, improving overall smelting safety. This product can be widely applied for new integral lining construction of various capacity coreless induction furnaces, and also fit for local lining patching and daily maintenance work in regular furnace overhaul cycles. It can be used for smelting carbon steel, alloy steel, cast iron and multiple non‑ferrous metal materials, covering most common smelting scenarios in modern foundry workshops.
Every batch of FYAC‑90CR Neutral Ramming Material will go through strict raw material inspection and finished‑product performance test before delivery. Gaoyou Fangyuan Furnace Material Factory implements complete quality control system to guarantee stable index consistency between different batches. Except bulk product supply, the factory can also provide practical technical suggestions including laying thickness reference, ramming operation points and furnace baking curve guidance for overseas and domestic clients. Correct construction and baking operation can further maximize the service life advantage of this neutral ramming mix.
With the continuous upgrading of foundry industry, more and more smelting enterprises tend to select high‑performance neutral monolithic refractories to replace conventional lining materials, in pursuit of longer furnace campaign, fewer shutdown maintenance times and lower comprehensive production loss. As a professional refractory manufacturer, Gaoyou Fangyuan Furnace Material Factory will keep focusing on real‑site feedback from end‑users, continuously optimize product formulas, enrich product portfolio, and deliver targeted refractory material solutions for high‑temperature manufacturing industries around the world.
