Luyang Energy-Saving Materials Ceramic Fiber, Modules and Mullite Bricks

Selection and quotation of Luyang materials: blankets and bulk fiber, Wildon modules, Crystal Shield fiber, boards and paper, rope, mullite bricks, coatings and PUREFRAX tubes.

Aluminum Silicate Fiber Blankets and Bulk Fiber

The Luyang standard blanket contains no binding agent and keeps its tensile strength in neutral and oxidizing atmospheres; its properties recover after drying. Bulk fiber is made by melting raw materials in a resistance furnace. The fire shutter blanket comes up to 1840 mm wide.

Fiber Modules and Wildon Monolithic Modules

The standard module is made of compressed needled blanket and anchored to the steel shell of the kiln; after installation it expands and closes the joints. Wildon 1260 and Wildon 1400 are uncompressed monolithic modules with cut faces for waste heat boilers, reforming and ethylene cracking furnaces.

Crystal Shield Alumina Fiber Blankets and Modules

Crystal Shield alumina fiber has a mullite crystal phase and is made by the colloidal method. The blankets serve at 1250–1500 °C, the hanging-anchor modules suit full-fiber linings at 1300–1500 °C. Composite modules of alumina and ceramic fiber blankets are designed for furnaces at 1250–1400 °C.

Vacuum-Formed Boards, Paper, Felt and Shapes

Luyang boards are vacuum-formed from ceramic fiber and are stronger than blankets and formed felt. The organic binder burns off at the first firing at about 200–300 °C. Paper is made by the wet process as soft, semi-hard, high-density and isolation grades. Felt serves expansion joints and gaskets.

Ceramic Fiber Cloth, Tape, Rope and Yarn

Luyang textiles are made of ceramic fiber reinforced with alkali-free glass filament or heat-resistant stainless steel alloy wire. Cloth serves fire curtains and cable protection, braided rope seals furnace openings and expansion joints of cracking furnace walls. Yarn is used to sew fireproof cloth.

Lightweight Mullite Bricks, Grades 23–32

Luyang mullite bricks come in grades 23, 26, 28, 30 and 32. They are made of high-purity refractory powder with organic composite filler by vacuum extrusion, high-temperature sintering and finishing. The bricks can directly contact flames, keep their volume when heated and can be cut to size.

Protective Coatings, Lightweight Concrete and Baker Nanoboard

Luyang 1200, 1400 and 1600 coatings based on alumina fiber are sprayed or applied by hand; they withstand up to 1700 °C and hot gas flows up to 80 m/s. Lightweight refractory concrete combines lightweight aggregate, refractory powder and binder. Baker nanoboard is a microporous insulation.

PUREFRAX Hot Gas Filter Tubes

Luyang makes PUREFRAX tubes under license from Unifrax (USA) of refractory ceramic fiber with a binder. Each tube is closed at one end and has a mounting flange at the other. They run continuously below 800 °C, short-term up to 1000 °C, with emissions below 5 mg/Nm³ and a service life of 5–8 years.

Fiber Type by Furnace Temperature

Luyang materials differ by fiber type. Aluminum silicate fiber is used for bulk fiber, blankets, modules, boards, paper and textiles.

Crystal Shield alumina fiber serves zones at 1250–1500 °C, while composite modules of alumina and ceramic fiber blankets suit furnaces at 1250–1400 °C. Wildon 1260 and Wildon 1400 monolithic modules have an abrasion-resistant surface for zones with higher gas velocity.

The grade is chosen by temperature, furnace atmosphere and gas flow.

Module Linings and Anchors

The Luyang standard module is cut from needled blanket and compressed on special machinery. Anchors on the back plate allow soldier-course or staggered installation. Once the bands are removed, the modules expand in all directions and form a seamless lining.

Alumina fiber modules use a hanging anchor. The anchors are fixed directly to the steel shell of the kiln, so module thickness, anchor type and layout spacing are checked against the lining drawing.

Bricks, Coatings and Lightweight Concrete

Luyang lightweight mullite bricks of grades 23–32 can directly contact flames and are cut to size for the working layer. The 1200, 1400 and 1600 protective coatings are sprayed or applied by hand, including onto hot surfaces without cooling the furnace.

Lightweight refractory concrete insulates industrial kilns and thermal equipment in metallurgy, machinery, power, petroleum and chemical industries.

Hot Gas Filtration with PUREFRAX Tubes

PUREFRAX tubes clean hot gases without electrostatic precipitators. The manufacturer lists the glass industry, biomass power generation, non-ferrous metals, coking, waste incineration, petrochemicals and cement.

Each tube tapers along its length for easier installation and dust cake removal; one end is closed, the other forms the mounting flange. Selection needs gas temperature and composition, dust load and filter housing dimensions.
